vTo all who m, may concern attachments for proved. attachment foreiectric switch tie vices, provided with memos for transforming on electric switch. mechanism of the push button type into a switch mechanism oi another type.

A further object of? my invention is to provide an improved att' chmcnt for electric switch devices adapted. to transform a switch mechanism of the push button tyge into a switch. mechanism of the pull-chain type.

Other objects and advantages of my im. proved construction will. liereiiicfter appear.

in the accompanying drawings I. have, for purposes of illustretioii, shown two forms which. my invention may assume in practice. My invention is not, however, limitmi to these forms but may" assume other forms.

in the views of these drawing-"s: Figure 1 shows a side elevation of on electric leinp equipped with one foriio of my improved switch actuating device. Figs. 2 and 3 show detailed views of this device. Fi 4. shows the operating. member of the device errcnged in an angular posit-ion with respect to its support. Fig. 5 shows mooilied form oi device. Fig 6 shows a further immliiiell fUlll'l. Fig. "l" shows 1,!

exon of the constructionshown r the figures oi the clrz rposes of illustration, shown my my prove-til switch actuating device apples. to a single puslrlmtton operated scrip switch lrieclmnism usecl in connection with an. electric lamp. in this construction the lump shell 1 is inclosecl in it resilient bend having a iilurality of resilient arms 2, eonnectecl together at one end as by means of a. sine-- eblc screw or bolt 3, will, on the o side of the shell, an opening through the push button 4 o l i switch I! extends. in this "form the operct serial No. 6565 53.

her 5 is pivoted at 6 upon a. pivot-supporting member 7, suitably swiveled around the opening in the banal through which the push button extends, as by meims of av rivet 8. Upon movement of the operating member 5 by means of a pull-clieiii, cord or other device 9, (lpel'fi'llli'lg .rnember is moved about its pivot to force the push button. 4i inward to make creek the circuii (unncctions of the switch mechanism.

In a preferred iorm the bend ericl arms 2 are formecl of one strip of resilient metal. "which is provided with enizirgerl portion 10 at a point spproiimetely opposite the point Where the arms are connected; by the screw 3.' This enlarged portion 10 may,

in a preferred. construct-ion, be substantially circular in form, and cutaway portions 11 may be provided at the points Where it is joined by the arms 2, in order to increase the resiliency of the parts. In a preferred form the enlarged portion 10 has it concave inner surface as shown in 3, the edges of the same being inclined tovverrl the lamp. shell. in :2, p1- "crrecl form the enlarged portion 10 is provided with a central opening through which extenils: e. suitable rivet or other device 8 having overtiirrierl eclges arranged to clamp the pivot supporting member 7 to the inner surface of the em largecl portion 10. This member 7 is prefcrcbly provided. with an enlarged booly per rioii 1.2 which, in a. preferred form, has an irregular shaped periphery illustrated as substantially star-shape in Fig. 2. As in the case of the enlarged portion 10, the portion 12 of the part 7 is also slightly conceve to conform to the shape 01 the member iii. In a preferred form the concave portier. 1% is connected to the portion 7 by means neck 13 of slightly recluceai Width, which so shaped. that the portion 7 lies in substantially parallel plane with the ends of the enlarged portion 10, permitting it to clear the flange on the lamp shell. The member 7 is preferably provided, with a plurality of forwardly extending pa allel. lugs 1 1', which are perforated near their encls to receive the pivot pin 6 about which. the operating member 5 is moved. in a preferred form the operating member 5 is formed in thr-"sl ape of a bell crank lever id made of a single piece of stamped metal. orni the inner end of the wiel. on upper lug or Q messes.

extension 15, which, when the operating member is in its up position, as shown in Figs. 1 and 3, rests against the member 7. The short inner arm of the bell crank member 5 is preferably provided with a cutaway portion 16 to permit a better grip upon the protruding end of the push button The outer end of the other arm of the pro truding member may be'of any desired length and is, in a preferred form, twisted, as shown, in order to strengthen it and'p'rovide a suitable support for the end bf the cord or chain 9. By the provision of the,

irregular shaped member'12 and the curvature of this'member andrthe enlarged portion 10, I am able to provide a device which is very firmly held infiposition; when the. spring arms are attached to the support, since the inner surface of the member 10 binds against the inner surface of the irregular shaped member 12 and thus effectually prevents accidental rotation of'this member and the operating member 5. If desired, by simply loosening the holding means 3 the operating member 5 may be arranged at any desired angle with respect to the arms 2, as shown in Fig. l, so that the switch mechanism may be readily operated from any de sired angle, the operating member being firmly held in any position to which it is moved by simply tightening the holding means 3.

When it is desired to operate a switch mechanism either to make or break thecircuit all that it is necessary to do is to pull down or operate the lever 5 by means of the chain or cord 9. The operating member moves about its pivot 6, and the cutaway portion 16 on its lower arm engages with the protruding end of the push button. As the operatin member is turned about its pivot this push button is pushed in to compress the springs within the switch mechanism, andat a predetermined point in its travel the switch mechanism is turned to make or break the circuit and the push button is returned to its normal position protruding from the shell. When. the switch mechanism is thus returned to its normal position the operating member 5 is automati- Cally swung backward by the push button about its pivot to the up position shown-in Fig. 1, so that it may be again operated by pulling downthe cord or chain.

In Fig. 51 have illustrated a modified form of actuating mechanism. In this construction I provide a disk 17 which may be formed of any suitable material and is arranged to be carried in substantially the same manner as the pivot carrying member 7, shown in Fig. In this construction 1'. preferably provide the disk 17 with an opening or slot 18 in its periphery, which is preferably slightly enlarged at its bottom, as shown n Fig. This slot is arranged to receive the last ball or link of the chain 9, or, where cord 1s used, the knot on the end of the cord. In this construction,

instead of using a pivoted lever I provide aprotrudmg cap 19 arranged to fit over the endof the push button. This cap 19 is preferably substantially cylindrical in shape and provided with a recessed. end 20 arranged to receive and act av guide for the chain or'cord 9. in operating this device apull upon the cord or chain, which has its en'ds fixed in the slot 18, acts to force in the cap 19,-which is carried by the-push button, to actuate the switch mechanism.

In Figs. 6 and 'Z I have illustrated a modified form of this device, wherein I have provided pluralit ofslots 18 upon the periphery of the disk, so that the switch mechanism m'ay be operated from :mydcsired angle by simply placing the end, of the cord or chain in the desired slot. ts in the previous construction, l: preferably it a cap 19 over the end of thepush button 4; and mount the disk 1? in the some manner as described in connection with Fig. 5. In this construction the cap 19 is preferably provided with a plurality of recesses 20 in order-to permit the cord to run through it in any position.

By the use of my improved attachment I am able to readily transform a push bulton operated switch mechanism into a switch mechanism ot'the pull-chain type. Further,

by my improved construction I am able to provide a device which may be readily and conveniently arranged so that the switch mechanism may be operated by a pull from. any desired angle. Further, by my improyed construction I am able to prevent any accidental turning of the parts. Further, by the use of my improvement the switch i'nechanism is always actuated by a pull in the some direction in the same mannor as a pull chain switch. The construction is an exceedingly simple one, and the device may be made of a small number of rugged parts at very small expense. cord or chain may be of any desired length, so that the switch mechanism may be located. in any desired pos ion and actuated with case, when desired. By my improved construction there is no strain placed upon any of the operating parts, and the cll'ort re quired to actuate the switch mechanism is very small.
